Abstract Despite its implications for businesses and consumer welfare, unfair competition law has received limited scholarly attention in Ghana. This article fills a significant research gap by examining Ghana’s legal framework for unfair competition, focusing on legislative measures and court decisions in an attempt to facilitate comprehensive academic inquiry into the subject. The article explores how Ghana addresses unfair competition in line with international standards, particularly Article 10bis of the Paris Convention and the Trade-Related Aspects of Intellectual Property Rights Agreement. It assesses how Ghanaian courts have developed unfair competition protection jurisprudence over time with co-existing statutory and common law regimes. Additionally, it highlights the challenges in applying the law and areas for improving it. The study demonstrates how Ghana adopts various approaches to unfair competition, comprising a single source statutory reference point which coexists with the common law tort of passing off. The statutory approach, alone or with the other approaches, meets Ghana’s international obligations. However, there is a need for coherence and effectiveness in the interaction between statutory law and common law principles. Understanding this interaction is essential for ensuring Ghana’s consistent and effective application of unfair competition laws.
